Paris with a 13 year old

Already searched the past and present archives on Chow and have a pretty good idea where we'll dine most days/evenings.

I need suggestions in 2 areas, tho'..................

*We would like to go to ONE spectacular fine dining restaurant <price no object-Michelin prefered-preferably French cuisine> during our stay that would be deemed enjoyable and make the whole experience unforgettable to a 13 year old on her first visit to Paris. A place with a beautiful room <flower arrangements a plus> excellent food and service ditto the wine list for us adults.

**We will be spending a full day in Disney-Paris. Can anyone recommend a pretty decent restaurant inside the park? International theme restaurants OK, but looking for the one with the best food possible under the circumstances that it's a place for tourists.

1/ Le Cinqand 2/The restaurants in Eurodisney are not bad, they're mostly expensive. Just check the restaurants on their website. The ones in the hotel are actually good, but do you want to take that kind of time and experience in a Disneyland day? I know I just pack food when I go.

As I said that was a couple of years ago, but the food and ambience were really good. Didn't try any of the other restaurants. Checking on the Disney site and trip advisor, it looks like it is better to book.
